Dorimanx Kernel for SGII-I9100
Supporting 5 ROM Platforms!
My kernel was based on SiyahKernel 4.0 long time ago in other realty,
Kernel Tree is 3.12.rc6-R101, + Samsung JB updates + my tweaks and lots of tuning!
Thank you Gokhanmoral for your great work in the past!
Warning!!!
Do not install this kernel on any Android version lower than 4.1.Y
Do a Nandroid Backup of your ROM before first try it! just in case
Constant OC will drain more battery! use low speeds on screen off! min 200/100 max 800
CPU will shutdown in case of over-volt or under-volt so be careful
I'm no responsible for any hardware damage or system corruption that can happen after using this kernel,
you are using this kernel from your own will and accept any responsibility by using it.
If you install this kernel your warranty will be void!
Of course you can be relaxed, I'm trying every release on my phone several hours before of release it so,
if something wrong, i will get the damage first, you get a tested and tuned working kernel...
« Thread rules
« Which kind of posts are allowed in this thread?
Report of bugs after test it personally and including the proper log (Please refer to the Voku's guide of How to report bugs for further information about logs.)
Feedback that could genuinely helps to the development of the kernel, for example tests of a new feature including a complete explanation, documentation and results.
Requests of new features for the next versions of the kernel with the proper explanation of why you expect to see it and why do you think that will be an improve to the kernel.
« Which kind of posts are not allowed here and belongs only to the discussion thread?
Battery life related, which include: Discussion of battery life, statistics of your battery life, screenshots about your configuration, your configuration itself (with the intention of help another users)
Reports of SOD if you undervolt / overclock your phone
General discussion about settings of the kernel, which include: Governors, schedulers, I/O, dual-boot, etc.
Requests of new features for the next versions of the kernel without the proper explanation of why you expect to see it and why you think that will be an improve to the kernel.
Bug reports with the proper attachments like logcat and kernel log (This is the exception, you can post it here and in the development thread, again, only with the log attached, otherwise the report will be ignored), please refer to the voku's guide of How to report bugs for further information about logs.
Deep sleep issues. Mostly of this issues are not kernel dependent, the rogue apps cause wakelocks and other weird behavior so, the first suggestion will be go to the BBS (Better Battery Stats) thread, install the app, and drop the log in there but as complement you can expose your issue here.

Kernel 5.84
*VOKU and me, we restored function that check DATA + CACHE file system before boot, for errors and damaged blocks and more.
it's can be requested for one time run by user via extweaks misc tab.
DO NAN DROID BACKUP VIA RECOVERY BEFORE ANY ATTEMPT TO USE IT! (if your phone will not boot, and you don't have backup, don't blame me for that)
If your data has allot of corrupted files. then first boot with this kernel will take longer! do not panic. let it work.
no more than 10MIN, if still no boot, then you need to restore your nand backup and never use this function!
your hardware is not ready for DATA partition clean up. forget it.
you will get new file /log-data and /log-cache
after boot you can check if you had any errors in data or cache.
To activate just "push the ATOMIC button " or push again to ABORT!
function will work after reboot, and never again, till requested by user.
If you do nan droid backup and then restore it, you restore all the errors and junk with it. (just for the info)
Goals for next builds:
Debug and find more code errors! (always something new)
Add cool features and tweaks
Extend battery life.
Boost performance.
« Installation
Download the file
Place it on your SD card
Reboot into recovery
Flash the file
Reboot
In case of a new installation on a non rooted or non recovery device:
You can Download ODIN 3.04 attached to page.
Reboot to Download mode (Hold Power + Home + Vol down, then vol up when you see the download menu)
Connect USB, wait until the drivers be installed
Install kernel via ODIN, choosing the option PDA, search for the file that you downloaded and push start
If all going fine the phone will reboot and you done

GESTURES!
Here you can download the app to set the gesture_set.sh script to make your own gestures.
*Added gestures script that connected with cortex and can be managed by user and system in harmony!
The script is located at /data/gestures_set.sh do not move it, if you have already any gestures scripts in init.d delete them and move your custom stuff to this script.
It will work with the screen on, and be shut on screen off, to get rid of one more loop that wait forever, we dont need it on screen off! So i give you 5 preconfigured gestures! max supported is 10! max finger touches supported also 10.
Script will be copied to data if not exist on boot, if exist then, nothing. You can shut this function in STweaks or restore to default gestures if you mess with it
On restore you will get backup of your current running file at /data/gestures_set.sh.bkp + gesture_set.sh.sec just in case.
PICK FOUND IN GOOGLE! It's not me
I am here for you so, ask, debug and comment!
Help me to make this kernel as good as possible!

Here I will post about things that exist in kernel.
First of all here are some guides made by VOKU also developer for this kernel.
Android: How to report bugs
How to use "ADB" - Command Line Tool
You get ZRAM SWAP.
In short, it's compressed RAM, that by using our mighty CPU compress 150MB of Real RAM into 300MB ZRAM!
This is simple math:
we have 848MB RAM, + 300ZRAM - 150 Needed for ZRAM = 1GB RAM
You can see it work by entering terminal app, or connection by ADB
And type:
free
you will see this..
Code:
[email protected]:/ # free
total used free shared buffers
Mem: 848164 801800 46364 0 13456
-/+ buffers: 788344 59820
Swap: 292968 23420 269548
in SWAP filed you see it exist and works!
Also there is one more advanced check
type:

==================================================================
Touch Recovery:
Made by ELITE DEVELOPER Gokhanmoral!
I have added tweaks and my configurations.
You can move in menu by finger, and by pushing arrows at the bottom, also hard keys work.
You can have 2 ROMS installed in one phone
See menu and check for full instruction on Developer Thread!
You can backup and restore / format / mount / install from ZIP / or from zImage!
You can set / reset your kernel profiles
there are 3:
Battery saver: reduced performance, but long battery life.
Default: normal performance, normal battery life
Performance: Boosted allot for performance, but faster drain of battery.
In order to use performance profile and not to drain your battery too much,
you need to set profiles in any app for CPU tweaking, that can give you profiles for:
Screen ON
Screen OFF
ON CALL
ON LOW Battery.
For screen ON you can use Full OC (200-1500) and have fun.
On Screen OFF: use 200-800/1000 speed
On Call use: 200-800 to save power.
On low battery use 200-1000/800/500 as you like..
================================================
You get tuned SQLite for CM9 or PURE ICS ROMS.
Its set to reduce the "sync command" when writing and reading tables in apps and system data.
So it's will "sync" on finish write, and not every small operation that its doing.
By this, read/write ( I/O) performance boosted allot!
If you install any other kernel after my, the sqlite will remain in ROM till ROM will be replaced.
================================================
More to be added later.

Kernel 1.0 -> 5.2
Code:
*Restored lot's of code that i and voku ported, to restore stability, much from that code was exp, so it's moved to EXP branch, i will test it offline.
*Changes to cortex for stability, see git.
*Messed with profiles save, should be ok now.
*Improved stability!
*Improved performance!
*Updated to 3.0.38!
*Fixed GPS
*Added wifi supplicant tuning to extweaks and to cortex.
*Added FIX for Korean GPS
*Added BT fix for SAMMY 4.0.4 ROMS by Gokhanmoral! TNX!
*More code porting for better deepsleep! and network fixes.
*Tuned hyper gov and renamed to HYPER!
*Updated to Samsung Update 5 + 6
*Lots of changes to TVOUT driver, it's may now work on custom roms!
*Removed ondemand, HYPER is the same gov but more advanced!
*Fixed intellidemand now it's stable.
*Ported more code fixes from 3.5-rc7
*Added new tweaks in extweaks and converted many to checkboxes.
*More patches to WIFI driver.
*Battery life improved allot! thanks to code changes that put more drivers to sleep!
*Removed KSM and ZCACHE from config, ZCACHE is damaged after merging with kernel 3.5-rc7 and KSM eat battery and dont really help. no big change in performance, still fast and smooth. (zcache no longer used in 3.x.x so we disable it too)
*Kernel is stable! 2 days with full cortex and performance profile.
*Updated to 3.0.37!
*I have ported lots of code changes from kernel 3.5-rc7 (about 2000+ code lines changed)
all about file system and cache memory and compression.
*VOKU has ported lots of new code for process control and kill + memory control. from 3.1.Y
*Fixed wakeup booster, it's more smart!, now i boost the freq to max but with your GOV not with performance, and add +25mV to all steps for time that wakeup booster works, then it's will set speed to normal and reduce voltage by -25 and all will be as you set.
*Cleaned code from unused functions.
*Extended light sensor and battery sensor pulling time, to reduce battery use, and CPU use (done by voku)
*Tuned voltage for HIGH steps 1000 --> 1500 added more +25mV each. for stability.
*Fixed the Touch keys timeout stuck at 5 sec. now should obey your settings.
*Added check if cortex background process is OFF or ON for real.
*Added new GOVs intellidemand and wheatley they are good for battery save, and can be fast if tuned via setcpu app! or they SLOW by default but very smart.
*Fixed all GOVS code about idle time statistics and wait for IDLE, should help reduce battery drain.
*Restored some define values to default, this small things can make big problems, we made some changes to them without fully understanding if it's OK or may damage some thing, like front camera!
*Kernel size is FULL, 8.10MB so very soon i will have to cut some tuning to gain more room for code changes...
*Fixed BLN still ON after main BLN switch off!
*Fixed small bug in kernel optimization.
*Tuned brightness for simple auto brightness (modded by VOKU)
*Improved stability and performance.
*File system corruption protection. by using FSYNC function to sync all changes to file system more often.
Added extweaks MISC option to disable the FSYNC to get little more performance, but reduce to less safe from damage file system (DEFAULT for all KERNELS!) this function is external! option will be updated only on reboot! not as you set it.
*Removed cortex background process for default and battery profiles, so user can use it or not. see extweaks, (without cortex, wake up booster + sleep gov change + dynamic GOV modding will not work!) for some ROMS, it's GOOD! since they get SOD all day with cortex ON, so try without, if OK, try with, if OK, have fun, if SOD, disable again.
It's ON for performance profile!
*Battery life improved.
*Added code fix that reduce CPU usage on idle to 1~15% on 100Mhz! was 15~30% now more battery will be saved.
*Rebuilded the root add/remove now it's used as buttons. install , remove , check
*Retuned Touch screen CODE, screen will not stuck now, 70% of SOD, not really stuck the phone, it's only the screen stuck! via adb i see that all OK! and system working as was, so now problem is fixed!
*New code fix for WIFI, now if not used and disabled in ROM, driver will cut power to WIFI chip! till now it's was still idle and drained power. not any more
*Finally i made my kernel STABLE! no more SOD and great battery life!
I have reverted from Linaro 12.06 GCC 4.7.1 builder to Android GCC 4.3 builder
that used to build all ROM and Default kernels!
So no more SOD! and battery is 1.1%/h -15mA :)
*Added more fixes to code from FLUXI kernel, TNX Myfluxi!
*Set 15 CPU freq steps for all profiles and removed settings to change it, there are many code trigers that depend on 15 freq steps, so best to have all for all profiles, then reduce the MAX freq to what needed, (already set)
*if you have added any INIT.D scripts that mess with my settings, REMOVED THEM, then test my kernel,
For some phones to low settings will always kill the phone,
I am asked all people that post INIT.D scripts in this thread, STOP/REMOVE. keep them to your self. thanks.

Fixed BLN test button.
cpu tab:
SWITCH to turn on/off wakeup booster and set the boost delay!
*Reverted last USB code update from NOTE, found that driver stuck after long charge and we can get to storage via USB, we have SG3 driver, so to mix them probably bad idea,

*Added new button at extweaks for checking current gps zone config.
*if you like to fix permissions, just push the button at extweaks misc and turn off the screen! fix will begin instantly! if you really need the phone, use it, but best to let it work top 2~3 min, depending on amount of mess and installed apps, it's done my 450 apps in 2 min :)
*we tuned profiles and voku added new stuff to conservative gov! so it's now the most saving battery gov! try it only for deepsleep (screen of gov)
it's slow, but this is what we need! less activity more battery!
*Vibrate should be OK now.
*now if phone is over 50c heat, and you turn off and on the screen. it's will auto drop to 1Ghz and to hotplug gov to cool off..
after temp will drop, and you turn screen on/off all your extweaks settings will be active again! so if was oc to max then you get it back :)

so its was to big to fit the boot partition, i had to move the modules out of kernel.
so from version 2.3 you cant update via tar and odin.
so use recovery only.
or update the supplied modules to /system/lib/modules/
if you install via recovery, nothing needs to be done.
in case of emergency use 1.1 kernel in tar, then go to recovery and update to 2.X :)

*Added fix for cpu stats and stalls(hangs).
*New WIFI driver + lots of changes to it already.
*support for NTT-Docomo variant (you will need to “echo 16 > /proc/sys/kernel/rom_feature_set” to get gps working.

Information Page
ZRAM (aka CompCache aka RAMZSwap)
ZRAM is an updated version formally known as CompCache and RAMZSwap. It was originally designed for 2.6.38.xx kernels, I have backported to our 3.0.xx kernel. ZRAM allows real-time compression of memory objects in RAM thus reducing memory pressure for the Linux kernel and can keep more apps in memory longer (more apps in RAM == better performance, less fetching from slower MMC or SDCard). Compression, however, is not Free. Some CPU cycles are required to do the compress/decompression, so there's a slight penalty for it. The original CompCache / RAMZSwap required a user space binary to control its behavior which adds additional penalty to performance, but the new version ZRAM eliminated the need for a separate dedicated daemon, thus reducing the overhead and increased performance from the old CompCache by 20%. Therefore, with the newer implementation of ZRAM interface, the performance penalty is almost negligible.

# ==============================================================
# Logic Explanations
#
# This script will manipulate all the system / cpu / battery behavior
# Based on chosen EXTWEAKS profile+tweaks and based on SCREEN ON/OFF state.
#
# When User select battery/default profile all tuning will be toward battery save!
# But user loose performance -20% and get more stable system and more battery left.
#
# When user select performance profile, tuning will be to max performance on screen ON!
# When screen OFF all tuning switched to max power saving! as with battery profile,
# So user gets max performance and max battery save but only on screen OFF.
#
# This script change governors and tuning for them on the fly!
# Also switch on/off hotplug CPU core based on screen on/off.
# This script reset battery stats when battery is 100% charged.
# This script tune Network and System VM settings and ROM settings tuning.
# This script changing default MOUNT options and I/O tweaks for all flash disks and ZRAM.
#
# TODO: add more description, explanations & default vaules ...
#
# ==============================================================
# Explanations
# ==============================================================
#
# oom_kill_allocating_task: If this is set to zero, the OOM killer will scan through the entire tasklist and select a task based on heuristics to kill.
#
# This normally selects a rogue memory-hogging task that frees up a large amount of memory when killed.
# If this is set to non-zero, the OOM killer simply kills the task that triggered the out-of-memory condition.
# This avoids the expensive tasklist scan.
#
# echo XXX > /proc/sys/vm/oom_kill_allocating_task;
# dirty_expire_centisecs: This tunable is used to define when dirty data is old enough to be eligible for writeout by the pdflush daemons.
#
# It is expressed in 100'ths of a second. Data which has been dirty in memory for longer than this interval will be written
# out next time a pdflush daemon wakes up.
#
# echo XXX > /proc/sys/vm/dirty_expire_centisecs;
# dirty_writeback_centisecs: The pdflush writeback daemons will periodically wake up and write "old" data out to disk.
#
# This tunable expresses the interval between those wakeups, in 100'ths of a second.
# Setting this to zero disables periodic writeback altogether.
#
# echo XXX > /proc/sys/vm/dirty_writeback_centisecs;
# drop_caches: Writing to this will cause the kernel to drop clean caches, dentries and inodes from memory, causing that memory to become free.
#
# To free pagecache:
# echo 1 > /proc/sys/vm/drop_caches
#
# To free dentries and inodes:
# echo 2 > /proc/sys/vm/drop_caches
#
# To free pagecache, dentries and inodes:
# echo 3 > /proc/sys/vm/drop_caches
# page-cluster: page-cluster controls the number of pages which are written to swap in a single attempt. The swap I/O size.
#
# It is a logarithmic value - setting it to zero means "1 page", setting it to 1 means "2 pages", setting it to 2 means "4 pages", etc.
# The default value is three (eight pages at a time). There may be some small benefits in tuning this to
# a different value if your workload is swap-intensive. (default 3)
#
# echo XXX > /proc/sys/vm/page-cluster;
# laptop_mode: laptop_mode is a knob that controls "laptop mode". When the knob is set, any physical disk I/O
#
# (that might have caused the hard disk to spin up, see /proc/sys/vm/block_dump) causes Linux to flush all dirty blocks.
# The result of this is that after a disk has spun down, it will not be spun up anymore to write dirty blocks,
# because those blocks had already been written immediately after the most recent read operation.
# The value of the laptop_mode knob determines the time between the occurrence of disk I/O and when the flush is triggered.
# A sensible value for the knob is 5 seconds. Setting the knob to 0 disables laptop mode.
#
# echo XXX > /proc/sys/vm/laptop_mode;
# rr_interval: rr_interval or "round robin interval". This is the maximum time two SCHED_OTHER (or SCHED_NORMAL, the common scheduling policy)
#
# tasks of the same nice level will be running for, or looking at it the other way around, the longest duration two tasks
# of the same nice level will be delayed for. When a task requests cpu time, it is given a quota (time_slice) equal to the
# rr_interval and a virtual deadline, while increasing it will improve throughput, but at the cost of worsening latencies.
#
# echo XXX > /proc/sys/kernel/rr_interval;
# dirty_background_ratio: Contains, as a percentage of total system memory, the number of pages at which the pdflush background writeback daemon will
# start writing out dirty data.
#
# echo XXX > /proc/sys/vm/dirty_background_ratio;

# swappiness: Swappiness is a parameter which sets the kernel's balance between reclaiming pages from the page cache and swapping process memory.
#
# The default value is 60. If you want kernel to swap out more process memory and thus cache more file contents increase the value.
# Otherwise, if you would like kernel to swap less decrease it. A value of 0 means "do not swap unless out of free RAM",
# a value of 100 means "swap whenever possible".
#
# echo XXX > /proc/sys/vm/swappiness;
# overcommit_memory: Controls overcommit of system memory, possibly allowing processes to allocate (but not use) more memory than is actually available.
#
# 0 - Heuristic overcommit handling.
# Obvious overcommits of address space are refused. Used for a typical system.
# It ensures a seriously wild allocation fails while allowing overcommit to reduce swap usage.
# root is allowed to allocate slighly more memory in this mode. This is the default.
# 1 - Always overcommit.
# Appropriate for some scientific applications.
# 2 - Don't overcommit.
# The total address space commit for the system is not permitted to exceed swap plus a
# configurable percentage (default is 50) of physical RAM. Depending on the percentage you use,
# in most situations this means a process will not be killed while attempting to use already-allocated memory but
# will receive errors on memory allocation as appropriate.
# overcommit_ratio: Percentage of physical memory size to include in overcommit calculations.
#
# Memory allocation limit = swapspace + physmem * (overcommit_ratio / 100)
#
# swapspace = total size of all swap areas
# physmem = size of physical memory in system
# vfs_cache_pressure: Controls the tendency of the kernel to reclaim the memory which is used for caching of directory and inode objects.
#
# At the default value of vfs_cache_pressure = 100 the kernel will attempt to reclaim dentries and inodes at a "fair" rate with respect
# to pagecache and swapcache reclaim. Decreasing vfs_cache_pressure causes the kernel to prefer to retain dentry and inode caches.
# Increasing vfs_cache_pressure beyond 100 causes the kernel to prefer to reclaim dentries and inodes.

#
# fifo_batch: Controls the maximum number of requests per batch.
#
# This parameter tunes the balance between per-request latency and aggregate
# throughput. When low latency is the primary concern, smaller is better (where
# a value of 1 yields first-come first-served behaviour). Increasing fifo_batch
# generally improves throughput, at the cost of latency variation.
# back_seek_max: This parameter, given in Kbytes, sets the maximum גdistanceג
#
# By default, this parameter is set to 16 MBytes.
# This distance is the amount of space from the current head location to the sectors that are backward in terms of distance.
# This idea comes from the Anticipatory Scheduler (AS) about anticipating the location of the next request.
# This parameter allows the scheduler to anticipate requests in the גbackwardג
nextג
# back_seek_penalty: This parameter is used to compute the cost of backward seeking.
#
# If the backward distance of a request is just (1/back_seek_penalty) from a גfrontג
# the seeking cost of the two requests is considered equivalent and the scheduler will not bias toward one or the other
# (otherwise the scheduler will bias the selection to גfront direction requests).
# Recall, the CFQ has the concept of elevators so it will try to seek in the current direction as much as possible to avoid the latency associated with a seek.
# This parameters defaults to 2 so if the distance is only 1/2 of the forward distance, CFQ will consider the backward request to be close enough
# to the current head location to be גcloseג
# fifo_expire_async: This particular parameter is used to set the timeout of asynchronous requests.
#
# Recall that CFQ maintains a fifo (first-in, first-out) list to manage timeout requests.
# In addition, CFQ doesnגt check the expired requests from the fifo queue after one timeout is dispatched (i.e. there is a delay in processing the expired request).
# The default value for this parameter is 250 ms. A smaller value means the timeout is considered much more quickly than a larger value.
# fifo_expire_sync: This parameter is the same as fifo_expire_async but for synchronous requests.
#
# The default value for this parameter is 125 ms.
# If you want to favor synchronous request over asynchronous requests, then this value should be decreased relative to fifo_expire_asynchronous.
# slice_sync: Remember that when a queue is selected for execution, the queues IO requests are only executed for a certain amount of time (the time_slice) before switching to another queue.
#
# This parameter is used to calculate the time slice of the synchronous queue.
# The default value for this parameter is 100 ms, but this isnגt the true time slice.
# Rather the time slice is computed from the following: time_slice = slice_sync + (slice_sync / 5 * 4 ג io_priority)).
# If you want the time slice for the synchronous queue to be longer (perhaps you have more synchronous operations), then increase the value of slice_sync.
# slice_async: This parameter is the same as slice_sync but for the asynchronous queue.
#
# The default is 40 ms. Notice that synchronous operations are preferred over asynchronous operations.
# slice_asyn_rq: This parameter is used to limit the dispatching of asynchronous requests to the device request-queue in queueגs slice time.
#
# This limits the number of asynchronous requests are executed (dispatched).
# The maximum number of requests that are allowed to be dispatched also depends upon the io priority.
# The equations for computing the maximum number of requests is, max_nr_requests = 2 * (slice_async_rq + slice_async_rq * (7 ג io_priority)). The default for slice_async_rq is 2.
# slice_idle: This parameter is the idle time for the synchronous queue only.
#
# In a queueגs time slice (the amount of time operations can be dispatched), when there are no requests in the synchronous queue CFQ will not switch to another queue
# but will sit idle to wait for the process creating more requests. If there are no new requests submitted within the idle time, then the queue will expire.
# The default value for this parameter is 8 ms. This parameters can control the amount of time the schedulers waits for synchronous requests.
# This can be important since synchronous requests tend to block execution of the process until the operation is completed. Consequently,
# the IO scheduler looks for synchronous requests within the idle window of time that might come from a streaming video application or something that needs synchronous operations.
# quantum: This parameter controls the number of dispatched requests to the device queue, request-device (i.e. the number of requests that are executed or at least sent for execution).
#
# In a queueגs time slice, a request will not be dispatched if the number of requests in the device request-device exceeds this parameter.
# For the asynchronous queue, dispatching the requests is also restricted by the parameter slice_async_rq. The default for this parameter is 4.
# ===============
#
# BFQ-Settings
#
# ===============
# timeout_sync, timeout_async: The maximum amount of disk time that can be given to a task once it has been selected for service, respectively for synchronous and asynchronous queues.
#
# It allows the user to specify a maximum slice length to put an upper bound to the latencies imposed by the scheduler.
# max_budget: The maximum amount of service, measured in disk sectors, that can be provided to a queue once it is selected (of course within the limits of the above timeouts).
#
# According to what we said in the description of the algoritm, larger values increase the throughput for the single tasks and for the system,
# in proportion to the percentage of sequential requests issued. The price is increasing the maximum latency a request may incur in.
# The default value is 0, which enables auto-tuning: BFQ tries to estimate it as the maximum number of sectors that can be served during timeout_sync.
# max_budget_async_rq: In addition to the max_budget, limit, async queues are served for a maximum number of requests, after that a new queue is selected.
# low_latency: If equal to 1 (default value), interactive and soft real-time applications are privileged and experience a lower latency.

2.Add/Remove governor
4.Fsync control
5.Add more TCP congestions
3.More features
HOW TO:
Here are some intructions/tips about how to play with the kernel.
Terminal is needed.
If you want to change the values,it needs su permission.
If you get 'Permisson denied',you need su permisson.
If the devices lost responses,hold power button 8s to reboot.
You can cd to the folder first,then do echos.
( CPU Freqs )
With DVFS,we cannot tweak min/max scale freqs via apps like SetCPU or nofrill.
but there are two ways you can change cpu freq:
by using this app
[APP][ROOT][4.0+] Performance Control - Open Source
Click to expand...
Click to collapse
or
by using terminal
cd /sys/power
Click to expand...
Click to collapse
For example: set 800Mhz as max limited
echo 800000 > cpufreq_max_limit
Click to expand...
Click to collapse
* When you switch on/off,power saving mode,this tweak will be overrided.
* If you want it to be permanet edit 05exp file in init.d.
No-fills CPU shows a wrong freqs
This is NOT issue. No-fills will show you Dynamic Min/Max scaling freqs,DVFS(dynamic voltage and frequency system) will adjust Min/Max freq according to system load.
Open SetCPU,it shows you real freqs.Or check sysfs directly.

ABBamp Audio
Please note that listening to too high volume music over 1 hour or more can damage your ears.
Too high volume can make your external speakers/headset overload or damage them.
First, why do i call it `AMP`?
Because most of our tweaks are about gain(volume)
Our codec is simple, It doesn't have any hardware EQ (although i want...)
ABBamp sysfs entries are in:
Quote:
/sys/kernel/abbamp
Click to expand...
Click to collapse
* Use RootExplorer to view this folder,there are lots files
Tweaks will take effects immediately!
Most tweaks will accept inputs like "on", "off" (no quotes)...
So, say "on" to enable this tweak, then this tweak will apply the value stored/inputed
View(cat) these files, most of them will give you useful infomation about this tweak.
They will show you the volume in dB of gain
`cd` to /sys/kernel/abbamp first then do echos, will be more convenient.
[AnaGain3] (Headset analog gain path):
Enable tweaks:
echo on > /sys/kernel/abbamp/anagain3
Click to expand...
Click to collapse
Disable tweaks:
echo off > /sys/kernel/abbamp/anagain3

Gain control: (min:0 ,max: 15) Lower value,higher volume (default: 0[+4dB])
echo left=?? > /sys/kernel/abbamp/anagain3
Click to expand...
Click to collapse
echo right=?? > /sys/kernel/abbamp/anagain3
Click to expand...
Click to collapse
Write both left and right channels:
echo gain=?? > /sys/kernel/abbamp/anagain3
Click to expand...

Not Killable Processes
This feature allows to define processes and system processes white-lists filled with the preferred process names and to not be killed by lowmemorykiller, unless it is absolutely necessary.
[APP][ROOT][4.0+] Performance Control - Open Source
Logcat
I have made android logger(logcat) as module to free more RAM.
Create a new init.d script:

#!/system/bin/sh
insmod /system/lib/modules/logger.ko
Click to expand...
Click to collapse
Then you can use logcat command.
EGL Driver
To use Mali hardware egl driver only:
Edit /system/lib/egl.cfg

0 1 mali

Init.d script
Please install busybox in system first
I recommend you install busybox via apps
Create a new folder named 'init.d' in /system/etc
Set the permisson of init.d foler to 0777(rwxrwxrwx) (at least has read and exec permission)
Set the owner to 0.0 (root root)
Put some scripts (any name you like) in init.d folder with permisson 0777 (rwxrwxrwx) (at least has read and exec permission)
Scripts with right permisson will be runned when system boots.
zRAM/SWAP
zRAM is optimized for Android. It is not lazy anymore.
Using zRAM will take a little CPU, because it needs to compress/decompress memory.
Recommended compressing about 18% of RAM, about 100 mb.
Setup disksize first: (example: 96mb= 96×1024×1024)
echo 100663296 > /sys/block/zram0/disksize
Click to expand...
Click to collapse
* Larger size more RAM will be compressed.
* Too large size might make phone lag
To enable:
Code:
mkswap /dev/block/zram0
swapon /dev/block/zram0
To check how many does it use:
cat /sys/block/zram0/num_reads
cat /sys/block/zram0/num_writes
cat /proc/meminfo | grep swap
Click to expand...
Click to collapse
* We can get other info in its sysfs
[SWAP]
1. Format/resize external SDCard via computer first.
Enable:
mkswap /dev/block/mmcblk1p1
swapon /dev/block/mmcblk1p1
Click to expand...
Click to collapse
2. Using a FILE as swap RAM: (Create a continuity file first)
su
cd /cache
dd if=/dev/zero of=swapfile bs=1024 count=81920
mkswap swapfile
swapon swapfile
Click to expand...
Click to collapse
Then we will have an 80mb swap RAM.

I see in your changelog you've changed RAM amount, AFAIK our GPU uses 120 MB of RAM. I wonder if it would be worth it to downgrade RAM amount for GPU to like 100? Or even 80 MB of RAM, so our system would have more, like 400 MB.

I have tried allocating 400MB to system and it worked but hd video playback doesn't work and games start to fc.so I set it to 390MB which is stable and doesn't have side effect.

Wow 400MB!!! I think I could not play games and he video in order to have 400mb of free ram!!
Inviato dal mio Xperia U con Tapatalk 2

Sure i'll add it..but can somebody give me confirmation that kernel is working or not?.

I have tried allocating 400MB to system and it worked but hd video playback doesn't work and games start to fc.so I set it to 390MB which is stable and doesn't have side effect.

Yes its working pretty good..
The games seem more responsive dnt knw why maybe a placebo effect..
But I guess u will have to work on it to tweak for gaming..
Hve tested it for hardly some time so cant say abt battery..
But this kernel looks really promising..
Keep up the development..
Good work..
Sent from my ST25i
this kernel is for stock right? because i'm getting bootloop on cm10
Wow any screen of ram(poxible totally free)

Maybe,I will upload alternate kernel with 400MB ram for user who does not
Play games or watch hd video.
Hey Everyone,
I'm by no means a pro at kernel building but I've put lots of effort into this kernel so I thought I'd share it with you. After a very long inner conflict period I've decided to post in the android development forum instead of the original android development. I've included features of my own as well as patches and other features of many other top notch kernel developers. I would prefer if you make your way over to my source (link below) and read the commits so you can get to know them and how they have contributed but alas I not that naive enough to think any of you really would actually go and do that so I've included a nice feature list in post 2 with proper credits (at least for the big stuff).
I am a huge fan of giving you options which is why I build my kernel with multiple toolchains and multiple sound options for you to test out and decide which option you find works best for you.
I also made a Release Folder that contains kernels that do not contain any CPU or GPU overclock to keep things more stable for you. This kernel is built with UBERTC 4.9.4 since I feel like that give the best battery. Choose this option for stability.
I frequently get asked if this kernel works with the many AOSP projects. The answer is YES! I haven't found an AOSP ROM yet that won't boot with this kernel. The only potential issue is that the ROM you flashed this kernel with has modified the ramdisk from stock or doesn't have a root containing sepolicy for Lollipop. Make sure to flash back to a stock ROOTED kernel and then flash UBER. My kernel uses you ramdisk while flashing for great ROM compatibility but sometimes this backfires.
Do not flash on CM or CM-based ROMs! This kernel is not currently compatible with those "CAF-based" ROMs.
WARNING!!! Even though I don't post anything unless it works (in this case on most if not all AOSP ROMs) I still don't want to be liable for user errors. In other words, if you flash one of these Kernels your warranty is void and I AM NOT RESPONSIBLE for any data loss or bricked devices etc.

- Merged latest Color Drivers for N5 (neobuddy)
- Changed Toolchains from SaberMod (Now partially closed source so that you cannot build for yourself anymore) to an AOSP-based open source toolchain called UBERTC. Many patches from Linaro have been included in source and also some GCC build fix patches from SaberMod to allow for the latest toolchain components. All sources are GPL and can be found [URL="https://github.com/UBERTC/"]https://github.com/UBERTC/[/URL]. New toolchains have less of a tendency to lag in scrolling and other screen transitions in comparison to SaberMod and I think are better suited for UBER.

Installation Instructions
1. For best results a install these kernel after a fresh ROM install (although it still should work if you don't do that)
2. Reboot into recovery (TWRP 2.8+ or compatible recovery)
3. Flash Kernel Zip
4. Reboot and let Settle for ~10 minutes (optional but recommended)
5. Navigate to system/etc/uber_v1.3.cfg using your favorite root file browser and change values based on descriptions to whatever you want.
6. Enjoy!!!
Note: In Android Lollipop while Superuser kinks are still being worked out you may need to reflash root after you flash kernel.

Solutions/Ideas to the Most Common Issues
I cannot seem to flash UBER Kernel why is that? Some ROMs come with these build.prop lines which are unacceptable to TWRP but work fine as far as the ROM goes. You will have to remove these lines from the build.prop for it to flash.
dalvik.vm.dex2oat-flags "--compiler-filter=interpret-only"
dalvik.vm.image-dex2oat-flags ""After you have installed the kernel you can re-add these lines to your build.prop. If you don't have these lines in your build.prop it is most likely a bad download.
I have RRs with this kernel but not with others, why is that? I have undervolted some other kernel features besides the cpu that you cannot change to save you battery. On some N5s (since not all are created equal) you may actually have to increase voltages on cpu or else you keep getting RRs. Try +25 across CPUs and see if that fixes your RRs. If not keep going down the list.
Having issues with Undervolting? The chief complaint about this kernel is that "I can't uV as much as I can with other kernels." I have undervolted other kernel features (ie cpu regulators) that you cannot change to save you battery. This makes it hard for you to uV the cpu voltages as far but rest assure you'll still be getting better battery for it. Also, be aware that undervolting is a little dangerous in this kernel because of the potential of data loss when dynamic fsync is enabled. If you do decide to undervolt make a backup first so when your phone crashes you can restore. Also be aware that most of the logs ending in wdog_reset are caused by too much uV so before you post a log that ends in wdog_reset please stop undervolting first to see if the RRs persist. Below -25 uV seems to be the point where most users experience issues. Also keep in mind that voltage is important in benchmarking. Many people are benchmarking at incorrect voltages for their devices. I have to add +25 mV to all values so that it doesn't RR during benchmark. Each phone is a little different so some of you may be fine as is and some of you may need to go +50 mV or even potentially more. You'll have to experiment to see where your phone's "sweet spot" is. I again recommend also disabling Dynamic Fsync until you have figured out where that sweet spot is to prevent data loss.
Why am I having issues with ROMs on MultiROM? From my experiences, Custom Kernels and MultiROM have always not played well together. Flashing a custom kernel on Internal ROM has never been an issue you try and flash a custom kernel on ROMs 2-whatever you have weird permission issues which can cause all sorts of problems for you (apps crashing, RRs, loss of root, etc). This is probably why the kernel sharing feature was added which is good but has it's own set of problems when using UBER. (See post directly below) To reiterate, this is not a bug in UBER or MultiROM just a slight incompatibility between the two we have to overcome by hand.
UBER works fine on Internal ROM but has issues on ROMs 2 and beyond when using MultiROM and sharing UBER why is this? UBER is not specifically geared for use in MultiROM, not because I don't like multiROM but simply because of Uber's nature. UBER uses showp1984's custom msm_mpdecision and thermal which conflict with proprietary mpdecision and thermal regulators and cause RRs if these files are present. During normal kernel flash these files are renamed and don't conflict with UBER. When you share this kernel during ROMs 2 and beyond can still be used safely if you know what you're doing. In order to allow ROMs 2, 3, and beyond to share the kernel you must delete N5 proprietary files found at system/bin/mpdecision and system/bin/thermal-engine-hh when running those ROMs. It is a fairly easy process, just install a Root File Browser, locate then, and delete. Normally in kernel flashing process I rename those files to mpdecision_bck and thermanl-engine-hh_bck for you so you never have to see or worry about them. If you use Sharing Feature on MultiROM you'll have to deal with these yourself. I apologize for this inconvenience but there is nothing I can do from my end. Flashing UBER on ROM 2 breaks it and sharing has problems until you remove these two files.
Why are certain apps crashing on me? Most likely it is due to Frandom. I have implemented Frandom by default in this kernel and to my knowledge I'm the only developer that does that by default. Some apps or mods may not be frandom compatible. Most are 100% compatible but not all. If you notice programs stop opening or are having constant reboots try removing 00_frandom from the init.d folder and reboot. I think for stable releases which I plan on posting on XDA this weekend I will not have frandom implemented by default but in nightlies it will always be implemented. Also if you keep having random reboots this is something to try as well.
Not booting? Maybe you have Ramdisk Incompatibility. This kernel uses your ramdisk. Most of the time that works well. Sometimes it does not. Make sure to flash http://goo.im/devs/Cl3Kener/HAMMERHEAD/KERNELS//STOCK-BOOT_IMAGE-4.4.3.zip and try again if it doesn't boot. If it still doesn't boot make sure to verify that it is not CAF. Some ROMs fail to mention they are CAF-based but they really are.
My phone crashed once during benchmarking or for no apparent reason and now keeps randomly rebooting. My guess is you have Data Corruption. If you crash your phone out benchmarking or have a frandom related RR and you still keep getting RRs you might have data corruption. This usually happens when you have Dynamic Fsync enabled because Fsync is disabled when screen is on. When testing I crash my phone all of the time and apps and things get messed up. Having a backup is good but if you don't want to waste time backing up all of the time you can salvage things still. Here is what I do when I've crashed the phone and continue to get soft reboots: 1) I install SD Maid from the Google Play store. (I have pro version so I can clean more but free version should work well enough) 2) I use SD Maid to clean all of the app data. (don't worry it is smart enough to not loose your passwords so you won't have to resign into your apps) Then I download ROM Manager by Koush. I don't actually use ROM Manager I just think it has the best permissions fixing feature of any app I've tried (including recoveries). I select the option Fix Permissions toward the bottom of the free version. It then prompts a reboot and then I reboot and life is good again.
I have battery drain when nobody else does.... help!!! Install a wakelock detector and figure out what is keeping your CPU awake. If it's an app. Fix permissions, clear app data, reinstall app, disable app, etc. until is stops having issues.
Still have problems? Search my Google+ community in the questions category. If you don't find anything see below:
ERROR REPORTING
I am always open to hearing about your errors although just telling me something went wrong without giving me details does me absolutely no good. So here are my expectations if you do want to complain about something not working:
1. Please list the ROM you are using,
2. The IO scheduler you were using
3. The CPU governor you were using
4. The CPU frequency range
5. What you have done to attempt to fix it.
6. If you were able to simulate it again using the same settings.
7. Anything else you think is applicable to the issue
I would also hope that you would consider trying some of the following things to fix your issue before you ever report it because most of these things will fix the problem without me even having to change a thing.
1) Fix file permissions using a program that does a thorough job. I recommend using the fix file permissions in ROM manager because it is the best I’ve seen. For the record, I don’t actually use ROM manager for anything other than fixing permissions. Please consider trying this first because it tends to fix most of the FC/RR/SOD errors you might have.
2) Make a backup and install a clean version of the ROM you are running and see if you are still experiencing those same errors. You may have corrupted files if you’ve been dirty flashing.
3) If that doesn’t solve it, redownload and reflash, maybe something got corrupted but it still managed to flash. This happens sometimes and I can cause you grief.
4) Pull a logcat. MAKE SURE TO DISABLE DYNAMIC FSYNC BEFORE LOGGING!!! LEAVING IT ENABLED WILL CORRUPT YOUR LOG!I know not everyone knows how to do this but you can learn if you check out this OP or if you aren't comfortable with using terminal commands to pull a log just install Bootlog Uptime and set it up to autocopy log on RR. Opening the program after crash will autocopy your log and you send it to me.

This makes USB to computer connections transfer current the same as the wall charger. (Classical version)
Faux123 added the a ability to change currents to 500 900 1200 1500 2000. Enable by doing this
To enable custom - echo 2 > /sys/kernel/fast_charge/force_fast_charge
Then
echo 1500 > /sys/kernel/fast_charge/fast_charge_level
change value 1500 to whatever you want (as long as it's one of those 5 values)
To disable - echo 0 > /sys/kernel/fast_charge/force_fast_charge

0 is disabled
1 is normal dt2w (bottom half of screen)
2 is full screen dt2w
echo "0" > /sys/android_touch/doubletap2wake
Sweep2Wake/Sweep2Sleep
This one is tricky because there are two files to change. If you want both only run
echo "1" > /sys/android_touch/sweep2wake
If you only want sweep2sleep you'll have to run this as well.
echo "1" > /sys/android_touch/s2w_s2sonly
To disabled run both run these commands but with 0s instead.
GPU Governor Toggle
Acceptable values are "performance" "simple" or "ondemand". Ondemand is default so I placed simple here. Performance will freeze system is placed at full OC (at lest for me so be careful!)

# dirty_ratio default is 20.
echo "40" > /proc/sys/vm/dirty_ratio
Set MPDecision Values
Note: Only change these values after you've played with them in your favorite kernel tuning app. I recommend figuring out your settings then finding these files with a root browser then you can fill these init.d lines in with your root browser of choice.

I recommend that you figure out what you like and then create your own init.d script like I did. Here is the link to my example Script. I have 99 appended to the front so that it will run last resetting any previously set settings.

Here is my init.d tweak folder. https://www.dropbox.com/sh/88sqwe9q018pcne/xCzZBKAJTt Make sure to give them a number in the front if you decide to add them. Like 01_blahblah or 02_blahblah.
will it work in all roms (aosp,cm,...)?
Nice. I'll give it a try (stock rom).
Finally.. Thanks man.. Will try ASAP and let you knw

What about changelog?
Bam ROM installed and working fine.Thanks for the work and greetings from Spain, HTCMania.
I've been running the linaro 4.7.4 version of Uber on Blue Lightning and it works great! Is there any reason I should switch to the 4.8.3 version?

Harhar, very funny
Sorry, I'm not very technical, but I'm interested in learning more about kernels. Aside from the bigger numbers, is there some sort of performance or efficiency difference between the two? Pros and Cons of each?
Much appreciated!

Well the op said that if a ROM didn't boot up on this kernel we are to let you know. Well guess what? Latest cm nightly doesn't boot up. That's because cm decided to merge a bunch of caf stuff and now virtually all custom kernel are unbootable. Just saying. :crying:

Does anyone else ecounter random reboots when locking the screen?
What scheduler and governor are you guys using on 4.8.3 for better performance? There's so many to choose from and I'm having a difficult time telling which ones work better.
Good kernel

Hey Everyone!
So once again I'm having to rebuild my kernel thanks to CM. I uploaded yesterdays kernels early this morning after good day of testing with Stock. I have now created a branch for Stock as a backup and I guess we'll see if somehow the new kernel with CM updates is still compatible later. I hope to knock out the whole things today which will be difficult because it looks like somewhere in the ballpark of 200-250 commits. Assuming I have an error 1 every 10 that should only take me about several hours to do.
Anyways, so someone asked about changelogs. It's not that I don't believe in super detailed changelogs but I find that unless it's a tangible features nobody really understands/cares which is why I just include major features on Post #2. I've include the link to my github source which I find it best because iif you don't understand the commit message you can just click on the commit and read about the changes. Or I guess if you really wish I can just grab a log and paste it here like this

0384859 Revert " DRIVERS: SLIMBUS: Initial OC of Slimbus"
Those were my changes yesterday. (I having a feeling most of you just skipped over it)
As far as which do I think is better I personally like bleeding edge (and it seems like most of you do too) so I run Linaro 4.8.3. To me it feels a little snappier (on stock that is, I use stock for any of the battery life tests etc). Battery life seems to be about the same between the two though so again it's not like a big deal one way or another. I just like to give you all options instead of only making one kernel. Because I have build scripts and a fast computer it takes me about 5 minutes to build one kernel so I can make both in about 10 minutes. That's no big deal for me. The part that takes the time is the patching, coding, tweaking, and testing.
Speaking of testing, I still haven't really figured out my dream IO and CPU Gov combo yet. I've been playing around alot and hopefully some of you will too. I can tell you that I always default to CFQ or BFQ with Ondemand since I really like those combos but I am also starting to like several other combos. If you find a combo you think is awesome please post it and a screenshot if you want to convince us it is good for battery or whatnot.
Anyhow, enjoy the 1/27 kernel from yesterday! I'll be working on a CM compatible kernel today.
Cheers!

Changelog
(old changelog)
R2.10
Build from R2.6 sources with re-added all changes in LiveOPP, cpufreq_limits module, some interfaces from 2.9.x (usb sw reset, PonKey emulator on voldown/up).
R2.9
Mali OC module v2.0:
added interfaces boost_hispeed1, boost_hispeed2.
added interfaces mali_threshold_freq_down and mali_threshold_freq_up
(new interfaces manual)
1) mali_threshold_freq_down/up:
echo new value to tweak it:
Code:
echo 150 > /sys/kernel/mali/mali_threshold_freq_up
2) mali_boost_hispeed(2)
Use command
Code:
echo idx=X > /sys/kernel/mali/mali_boost_hispeed2
to tweak its freq.
following command is to tweak its threshold:
Code:
echo threshold=220 > /sys/kernel/mali/mali_boost_hispeed2
partially re-enabled touchboost (it actually was enabled even on 2.7.4, but I forgot to mention)
reverted suspend/hibernate/freezer etc. commits to hopefully fix reboots issue in deepsleep
fixed APE_25_OPP (in suspend it actually used APE50 previously)
minor fixes in cpufreq_limits driver
R2.8
Mali OC module v2.0(detailed description in 3rd post):
added interfaces boost_hispeed1, boost_hispeed2.
added interfaces mali_threshold_freq_down and mali_threshold_freq_up
partially re-enabled touchboost (it actually was enabled even on 2.7.4, but I forgot to mention)
reverted suspend/hibernate/freezer etc. commits to hopefully fix reboots issue in deepsleep
fixed APE_25_OPP (in suspend it actually used APE50 previously)
minor fixes in cpufreq_limits driver
(2.7.6)
- fixed broken GPU scaling algorithm (removed /sys/kernel/mali/mali_scaling_dynamic)
(2.7.5)
- partially reverted LiveOPP voltage autocalibration
- fixed unstable mali tunables and added interface mali_scaling_dynamic
Code:
echo 1 > /sys/kernel/mali/mali_scaling_dynamic
When mali_scaling_dynamic is used, mali will scale between mali_boost_low and mali_boost_high using all steps between these mentioned. mali_stats provides statistics about mali utilization on each step.
- removed some GPU freq steps
(2.7.4)
- new governor Dynamic (thanks to mkaluza)
- new GPU scaling algorithm (thanks to 1N4148 ) - ondemand-like GPU governor
- LiveOPP: reworked avs-based varm recalibration algorithm
(2.7.3)
added governor OndemandPlus (thanks to boype)
removed governors with hotplugging support
added interface to tweak PLLDDR freq on suspend:
Code:
echo on > /sys/kernel/cpufreq/pllddr_raw
To control freq are used raw PLLDDR register values:
Code:
echo suspend=0x000050158 > /sys/kernel/cpufreq/pllddr_raw # 675 MHz
Code:
echo resume=0x000050168 > /sys/kernel/cpufreq/pllddr_raw # 798 MHz
PLLDDR freq can be checked via
Code:
cat /sys/kernel/liveopp/pllddr
Settings applies after 3 sec after suspend/resume.
Too low suspend or too high resume value may cause reboot. Please note that this setting still experimental and unstable itself, so it's disabled by default.
adjusted some GPU OC defaults
fixed BT issues
(2.7.2)
- fixed pllddr_cross_clocks instability
- removed unneeded DDR_50_OPP requirement on screen on (should prolong battery lifetime).
2.7

improved hotplugging mechanism
updated RCU system
kernel scheduler
memory management
etc...
LiveOPP:
recalibrate varm and vbbx on boot (better stability)
added interface to OC some clocks that depends on PLLDDR
reimplemented sweep2wake and doubletap2wake (thanks @Meticulus)

- better RAM performance with tiny cost CPU. Boot time will be increased by 3 sec, it's ok.
uploaded kernel for s6d.
R2.6
ABB-charger:
reverted most of changes. It's only uses custom voltage table, termination current 150 mA and some other tweaks, provided by ace2nutzer.
added tweakable interfaces for termination current(better battery lifetime).
LiveOPP:
added most ape_25_opp switch interface
added steps 85, 350, 450 MHz.

added state APE_25_OPP, used only with screen off(originally introduced by mkaluza, adapted for codina by me)
allowed change APE_OPP and DDR_OPP from LiveOPP
changed step 1228 MHz -> 1248 MHz (may cause reboots, need to find out optimal voltage)

Kernel Tweaks:
(GPU/CPU undervolting and related tweaks)
Undervolting the CPU/GPU will bring battery savings but possible instability.
1) to undervolt CPU use ChronoKernel app or via init.d scripts:
Code:
echo *cpufreq* varm=xx > /sys/kernel/liveopp/arm_summary
for example, following sets voltage varm=0x10 for 200 MHz:
Code:
echo 200000 varm=0x10 > /sys/kernel/liveopp/arm_summary
or
Code:
echo 200000 varm-=10 > /sys/kernel/liveopp/arm_summary
(default varm voltage for 200 MHz is 0x1a but, code above sets 0x1a - 0xa(10) = 0x10 )
2) to undervolt GPU use init.d script:
Code:
echo x vape=yy > /sys/kernel/mali/mali_dvfs_config
Example:
Code:
echo 2 vape=0x1c > /sys/kernel/mali/mali_dvfs_config
"2" stands for DVFS idx (look at mali_boost_high/mali_boost_low).
To prevent overriding of such settings by ChronoKernel app, add line to your init.d script after GPU undervolting
Code:
chmod 444 /sys/kernel/mali/mali_dvfs_config
Don't change voltage of both GPU/CPU at the same time - otherwise if you'll get reboot if won't know what it caused. The same is for different frequencies - if you'll change voltage of too many steps you won't know which frequency caused reboot. It's not easy process, though, following method simplifies it: https://github.com/mkaluza/i9070_kernel_CoCore-E/wiki/Undervolting-janice .
3) Custom LiveOPP table.
By default some LiveOPP steps such as 100, 200, 500 ... MHz aren't used. You can re-enable those by following way:
Code:
echo 200000 enable=1 > /sys/kernel/liveopp/arm_summary
Or use CK app instead. Don't enable it unless it uses the same voltage as 400 MHz. The same is for the rest frequencies - until some of them uses same voltage, no point to enable steps with lower freq. I've added 100 MHz just to further make some tests with it once again. It can't use lower varm than 200 MHz - that's why it's disabled by default. Furthermore, not all phones well keep undervoltage, that's why 100-400 MHz steps uses same stock voltage varm=0x1a.
UPD. thanks to @borkins for this nice editor LiveOPP ARM steps: http://forum.xda-developers.com/showpost.php?p=60311291&postcount=2921
(CPU freq management tweaks)
CPU freq. limiter for screen OFF, adjust it via:
Code:
SYSFS=/sys/kernel/cpufreq/cpufreq_limits_on_suspend
echo min=100000 > $SYSFS
echo max=400000 > $SYSFS
echo on > $SYSFS
Too low frequency may cause freezes after wakeup and sound scrathes. If you use Dynamic govermor, it make no sense to use cpufreq limiter, because Dynamic already takes care about CPUfreq usage optimization. For more, read wiki.
Input boost
This feature has been originally written by zwliew.
Not all governors support input boost. Supported governors: ondemand, interactive, conservative, ZenX, lionheart and some others. Dynamic governor has its own boost interface.
Default boost frequency is 400 MHz.
Code:
echo 450000 > /sys/kernel/cpufreq/input_boost_freq # echo '0' to disable
echo 35 /sys/kernel/cpufreq/input_boost_ms
(BackLight Notification)
To configure time intervals of BLN blinking type(bln_ondelay stands for time of blink and bln_offdelay - delay between two blinks):
Code:
echo bln_ondelay=500 > /sys/kernel/bln/blink_mode
echo bln_offdelay=6000 > /sys/kernel/bln/blink_mode
Make sure BLN enabled:
Code:
echo 1 > /sys/class/misc/backlightnotification/enabled
# to enable bln_wakelock.
echo on > /sys/kernel/bln/bln_wakelock
Use /sys/devices/virtual/misc/backlightnotification/blink_mode to changes modes.
Blink modes:
0 = no blinking
1 = blink backlight only
2 = blink backlight + rear cam flash
3 = blink rear cam flash only
(Module autoload)
Now there is a simple way to load modules at boot. Just move needed modules to /system/lib/modules/autoload and reboot device(or execute /etc/init.d/00autoload)
(DDR overclock)
This feature has been developed by me and allows you to improve DDR and GPU performance. Please note, that DDR OC might work unstable and cause filesystem corruption. Though, DDR clock of 975 MHz has been highly tested and should work fairly stable on most devices.
Overclocking DDR over 975 MHz is highly NOT recommended, especially in case if you not sure that you can deal with possible consequences.
How to OC DDR:
1) by using
this script .
2) by using Terminal Emulator(in example below 975 MHz):
Code:
echo 0x5017f > /sys/kernel/liveopp/pllddr_oc_on_suspend
This setting will be applied right after disabling screen.
(Minimum APE/DDR OPP on screen on)
This feature has been developed by me and allows to set minimum APE/DDR OPP states which are used when screen is ON. APE controls many systems such as an image, video, audio system etc. DDR OPP determines performance of DDR. Default values are APE50 and DDR50. Lower states(APE25/DDR25) reduces power consumption, but may cause graphical glitches like screen blinking or filling it by vertical grey lines. If you don't have mentioned effects, it's recommended to use APE25/DDR25:
Code:
echo ddropp=25 > /sys/devices/pri_lcd_ws2401.0/mcde_screenon_opp
echo apeopp=25 > /sys/devices/pri_lcd_ws2401.0/mcde_screenon_opp
* if you don't have folder /sys/devices/pri_lcd_ws2401.0, use /sys/devices/pri_lcd_s6d27a1 instead.
(Screen refresh rate)
This feature has been developed by cocafe and modified by me. Lower lcdclk frequency cause less power usage, but too low values makes system unusable.
Following command allows to change screen refresh rate:
Code:
echo x > /sys/kernel/mcde/lcdclk
use
Code:
cat /sys/kernel/mcde/lcdclk
to see supported lcdclk modes. Default mode is 60 Hz which is recommended in most typical cases. If you've screen tearings, blinking etc. change resresh rate mode to "60+ Hz":
Code:
echo 0 > /sys/kernel/mcde/lcdclk
(ABB charger tweaks)
added tweakable interfaces for termination current. To adjust it type(just an example):
Code:
echo 90 > /sys/kernel/abb-chargalg/termination_curr_1st
echo 70 > /sys/kernel/abb-chargalg/termination_curr_2nd
curr_2nd should be less or same as curr_1st. Lower values prolongs battery lifetime, but also slows battery charging.
Default values are curr_1st == curr_2nd == 150 mA. Please note, too low values maybe aren't usable.
(Dynamic FSync)
This feature has been developed by Faux123 and allows to dynamically manage the synchronous writes performed on file system (FSync).
It uses asynchronous writes when the screen is on, instead of synchronous writes, to have better performance and a slightly lower battery drain, while when the screen is off the synchronous writes are re-enabled to flush all the outstanding writes and prevent possible data loss.
How to enable/disable the Dynamic FSync (default enabled):
1) By downloading and using Trickster MOD
2) By directly editing the file /sys/kernel/dyn_fsync/Dyn_fsync_active and setting 1 to enable the dynamic fsync, 0 to disable it (note that set value will be lost after a reboot/shutdown)
3) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable the dynamic fsync feature
Code:
su
echo 0 > /sys/kernel/dyn_fsync/Dyn_fsync_active
- Or run this command to re-enable the dynamic fsync feature
Code:
su
echo 1 > /sys/kernel/dyn_fsync/Dyn_fsync_active

(Software CRCs)
Disabling software CRCs gives you a slight bump(10-30% is what they say) of MMC performance, at the cost of a possibility of your Ace 2 freezing randomly.
Code:
echo 0 > /sys/module/mmc_core/parameters/use_spi_crc

(Dynamic dirty page writebacks)
This feature has been developed by Christopher83 and allows to dynamically manage the dirty page writebacks with two different intervals, one when the screen is on and another when the screen is off.
It is based on a commit of Francisco Franco, but instead of using hard coded values and of disabling at all the dirty page writebacks while the screen is on (possibility of data loss).
By using a higher interval we have better performance and less battery consumption, with a very low risk of data loss.
How to customize the dynamic dirty page writebacks feature (default disabled):
Three new procfs parameters are exposed inside /proc/sys/vm path:
- dynamic_dirty_writeback is the activation status of this feature, set 1 to enable it, set 0 to disable it and use the standard behaviour
- dirty_writeback_active_centisecs is the interval for the dirty page writebacks when the system is active (screen on), the default value is 1500 centisecs (15 seconds)
- dirty_writeback_suspend_centisecs is the interval for the dirty page writebacks when the system is suspended (screen off), the default value is 500 centisecs (5 seconds)
1) By directly editing one of the file written above inside /proc/sys/vm and setting the preferred value (note that set value will be lost after a reboot/shutdown)
2) By using Terminal Emulator (note that set value will be lost after a reboot/shutdown)
- Open Terminal Emulator
- Run this command to disable the dynamic dirty page writebacks feature
Code:
echo 0 > /proc/sys/vm/dynamic_dirty_writeback
- Or run this command to re-enable the dynamic dirty page writebacks feature
Code:
echo 1 > /proc/sys/vm/dynamic_dirty_writeback
- Run this command to set customize the two intervals (30 seconds while the screen is on, 10 seconds when the screen is off)
Code:
echo "3000" > /proc/sys/vm/dirty_writeback_active_centisecs
echo "1000" > /proc/sys/vm/dirty_writeback_suspend_centisecs
(Storages switch)
By default, this kernel comes with internal and external storages switched. You can revert this behavior, by changing the line
Code:
use_swap=1
to
Code:
use_swap=0
in file /ramdisk/fstab_specs.txt and flashing the kernel package. This setting will remain until you format /ramdisk partition.
(Tweak app)

How to install kernel with F2FS support:
For those who don't know what F2FS is, check these links out:
General info
Benchmarks
Warnings
1. Make sure you have a standard kernel for backup that uses ext4 just in case. If anything goes wrong, just install the backup kernel and reboot to recovery.
2. You will have to wipe your /data and /cache partitions for this. Basically factory reset.
3. For 2, you could try to backup data and restore after formatting. I haven't tried this but I could work.
Click to expand...
Click to collapse
Installation method of kernels with full F2FS support:
Before installation make sure that you have at least ~25% free space on each partition that will be formatted to F2FS.
for CWM:
make backup
format /system partition to F2FS (and also /data and /cache if you didn't do it before)
restore /system partition
for TWRP
disable md5 generation
make backup of /system
find backup folder, run terminal and rename file system.ext4.win to system.f2fs.win (it won't work via filemanager)
Code:
mv system.ext4.win system.f2fs.win
format /system as f2fs
restore backup
Then install kernel.
To install kernel on ROM that isn't supported by installer:
(supported ROMs):
Stock ROM 4.1.2
CyanogenMod 10.1*
CyanogenMod 10.2*
CyanogenMod 11*
CyanogenMod 12
* most ROMs that based on this ROM are also supported. Despite of that some ROMs are supported, they can work incorrectly due to difference in their initramfs scripts(ramdisk).
1. Install needed ROM first,
2. Type following command in terminal emulator:
Code:
cd /
find . -xdev | cpio -o -Hnewc | gzip -9 > /sdcard/x.y.z.cpio.gz
where x.y.z is OS version (for example - CM11-based ROM - 4.4.4.cpio.gz)
3. put this file in installer at osfiles/x.y.z/ (e.g. osfiles/4.4.4/4.4.4.cpio.gz)
4. install kernel
To install a new ROM that is not F2FS compatible:
Use EXT4 to F2FS converter script
or edit the updater-script as follows
(manual method)
1. Replace strings
"mount("ext4", "EMMC", "/dev/block/mmcblk0p3", "/system");"
with string
"run_program("/sbin/busybox", "mount", "/system");"
2. Replace string
"format("ext4", "EMMC", "/dev/block/mmcblk0p3", "0", "/system");"
with string
"run_program("/sbin/mkfs.f2fs", "/dev/block/mmcblk0p3");"
3. Add string
"run_program("/sbin/busybox", "mount", "/data");"
after strings
"run_program("/sbin/mkfs.f2fs", "/dev/block/mmcblk0p3");"
"run_program("/sbin/busybox", "mount", "/system");"
4. Add string
"unmount("/data");"
before string
unmount("/system");

chmod 0644 /sys/module/lowmemorykiller/parameters/debug_level
echo "0" > /sys/module/lowmemorykiller/parameters/debug_level;
works miracles in my case, especially second one, imho it would be hard to use different values, i was trying different setups for YEARS(with this machine), so it is not just random throw. Bigger LMK REALLY makes things worse here. It usually has tremendous influence over fluidity of gui, and whole sys.

This kernel based on stock CM kernel by TeamCanjica, and it's have same changes.
Damn, I was so excited to see a new kernel, but I noticed that it's actually for 4.1.2. I almost flashed it on a 4.4.3, not that it would have been such a tragedy.
Is there gonna be a version for the KitKat ROMs?

OK. I've got another question for you. Are you gonna add "lagfree" between the governors you already added, because that's probably one of the best governors a kernel can have ?
This is for stock samsung JB?
yes it is
Even if in the download section it says 4.4.2, I flashed the kernel on a Carbon 4.4.3 and it's working like a charm. The only thing that doesn't show up correctly is both frequency bars in "performance". It shows 0MHz max, 0MHz minimum, but if you set the minimum to 600MHz, for example, the frequency will run at 600 minimum, even if it shows 0.
five attempts and each time bootloop and recovery keys do not work.

If you added "lagfree", you'd be the first on to do it, so it would obviously be amazing and it would make you a better developer than others, of course.
EDIT: About the frequency thing, for me it shows 0MHz probably because I've got kitkat 4.4.3. Everything else's working fine.

I have no idea what caused this problem. Because on stock kernel and CM kernel i did not have this problem. Try to remove this folder and create text file with same name.
Would love to see lag free if anyone could make possible
